摘要:
The present invention relates to the structure of a bipolar plate for direction methanol fuel cell, the shape of a flow path and a fuel cell including them, more particularly, to the structure of a bipolar plate for direct methanol fuel cell using a flow path with a dispersion structure not the existing serpentine type for supplying a fuel to the new bipolar plate and functioning as a collector and the shape of a flow path. According to the present invention, a fluid flow resistance is decreased and a direct reaction region of a fluid and an electrode catalyst is increased in a bipolar plate, and therefore the performance of a fuel Cell can be improved.
摘要:
The present invention provides an electrode binder for a polymer electrolyte membrane fuel cell which includes a hydrocarbon-based polymer and a water-soluble polymer acting as a porogen, a porous hydrocarbon-based electrode catalyst layer including the electrode binder, and a method of manufacturing the same. Because of the use of the porogen, the pore size and porosity of the hydrocarbon-based binder catalyst layer are optimized, and bondability of a hydrocarbon-based membrane electrode assembly is enhanced. The present invention also features a fuel cell manufactured using the porogen.
